My doctor recommended adding fish oil years ago, this is the only brand I will take. At first I tried anything that wouldn't have the fishy burpy aftertaste and this is the only one that really doesn't have it. My blood pressure is perfect now after years of battling high BP, and my cholesterol levels are going in the right direction. I believe this is a high quality brand, worth the extra money, although a better price can't be found anywhere other than iherb
